That is, when one or more cameras are installed at an appropriate position on the copyboard 100 to acquire an image of the writing pen, and a color label such as red, blue, and black is attached to the writing pen surface, the image processing unit 131 may be used. The color information of the writing pen can be extracted.

The color code generator 133 reads and outputs color code information corresponding to the color information extracted by the image processor 131. To this end, a table in which color information and color code information corresponding thereto are mapped is stored in a memory 139 which will be described later.

Meanwhile, the coordinate calculation unit 135 calculates and outputs the position coordinates of the writing pen from the signal output from the pen position detection sensor installed on the frame of the copyboard 100. The coordinate calculation unit 135 calculates the position coordinates of the writing pen by using a calculation program stored in the memory 139.

For reference, in order to calculate the position of the writing pen moving on the copyboard, as already known, the writing pen with an ultrasonic transmitter is attached, and a pen position detection sensor that transmits an infrared signal when receiving an ultrasonic signal and detects the reflected signal.
